Abstract
[Problems to be Solved] In a synthetic resin container closure of a type which includes a body and a tamper evident bottom portion connected to the body via a plurality of breakable bridge portions arranged with spacing in a circumferential direction, and in which the body continues to be connected via unbroken connecting pieces to the tamper evident bottom portion continuously mounted on a mouth-and-neck portion of a container even after the bridge portions are broken to remove the body from the mouth-and-neck portion of the container, an improvement is made so that the container closure can be applied, without posing problems, even when the ascent distance of the body when removed is relatively long.[Means to Solve the Problems] Each of the unbroken connecting pieces is in such a form as to include two tilting portions whose tilting directions are opposite to each other.
